Grounding ring

Abstract

Apparatus for discharging accumulated electrostatic charge from the human body includes a conductive ring to be worn on a finger. A first connector is attached to and electrically connected to the conductive ring. A cable with a mating connector plugs into the first connector. A second connector at the other end of the cable is connected to ground. A series resistor, located in the mating connector housing, limits current flow to a safe level in the event the user comes into contact with a high voltage high current source.

We claim: 
     
       1. Apparatus for electrically contacting the human body at a finger, comprising in combination: an electrically conductive finger ring, engagable with said finger, for electrically contacting said finger;   an electrically conductive connector ring having an aperture, said connector ring being electrically connected to said conductive finger ring and attached to the outside of said conductive finger ring;   an electrical connector plug, removably inserted into said connector ring, said connector plug having a substantially longitudinal slot and a retaining flange;   an attaching flange attached to said connector plug;   a housing having a cavity, said cavity having an internal groove, said attaching flange being inserted into said internal groove;   said housing including two complementary parts, said parts having an external groove;   a snap ring, inserted into said external groove, to join said complementary parts; and   a resistor, located in said cavity and electrically connected to said connector plug.
